What values for email "delivery-status" exist?

I'm creating a C# console app that will get emails from an Exchange mailbox, check to see if they are 'bounce back' emails and if so filter them as either 'hard errors' (where the delivery-type action is 'failed') or 'soft errors' (where the action is 'delayed'). Any emails not caught by this (such as 'unsubscribe') are then forwarded to a distribution list so various employees in my company can read those emails and take manual action as required.

My question is: what other types of delivery-status are there? 'Failed' is an obvious one I will work with (by locating and removing their record in my database, which is used to create recipient lists), and 'Delayed' is an action I can simply ignore for the most part.

What other actions are there that could be caught prior to forwarding on emails that need human interaction? Is there a list somewhere? Obviously I tried Google first, and then searched here, but no joy.

I refer back to the SMTP protocol documents:

Mail System Status Codes
http://www.ietf.org/rfc/rfc1893.txt

The first digit is the overall success or failure of message delivery.
2.X.X   Success
4.X.X   Persistent Transient Failure (soft-fail)
5.X.X   Permanent Failure (hard-fail)

The second gives the general reason why a message has failed delivery
X.0.X   Other or Undefined Status
X.1.X   Addressing Status
X.2.X   Mailbox Status
X.3.X   Mail System Status
X.4.X   Network and Routing Status
X.5.X   Mail Delivery Protocol Status
X.6.X   Message Content or Media Status
X.7.X   Security or Policy Status

The third gives specific reasons why the message failed.

Example:
5.2.2   Mailbox full

If you're looking for Exchange-specific delivery status codes, you can find those here:

While I was specifically looking for values of "Action" I was able to adapt my code to use extract the status code from my email object instead, making this posts hyperlink the most useful for what I need. I can now identify 'soft' errors vs. 'hard' errors by their status code.

Thanks
